Deprecated Semantic Scholar API endpoint

[hornlukas]

Hi there,

I noticed recently that the Semantic Scholar integration stops returning results when searching by DOI, which is done when using the refine method.

It looks like the issue is the /v1/paper endpoint, which seems to be deprecated now. I played around with it locally and found that switching the endpoint to /graph/v1/paper got everything working again.

However, the new endpoint has quite some rate limits without an API Key. So it may be worth looking into how to handle that (maybe strategies like exponential backoff for retries?)

Thanks for looking into it and let me know if and how I can help!

That's great! If you could submit your changes to use the new endpoint as a PR, that would great!

The Semantic Scholar integration is used often and it is a shame that it's now broken
